Description
The Lennox 69W40 is an OEM replacement 205°F limit control engineered to protect Lennox heating systems from dangerous overtemperature conditions. When supply-air or heat exchanger temperatures exceed the 205°F setpoint, this limit control interrupts the burner circuit, preventing equipment damage, nuisance shutdowns, and potential safety hazards.
Key Features
- OEM Lennox replacement part — ensures proper fit and reliable operation
- 205°F limit setpoint for precise high-temperature protection
- Interrupts burner operation upon overtemperature detection to safeguard the heat exchanger and system components
- Designed for straightforward drop-in replacement in compatible Lennox furnace and heating applications
- Durable construction for long service life in demanding HVAC environments
Why Use an OEM Limit Control?
Using a genuine Lennox replacement limit control ensures the safety circuit operates exactly as the equipment was designed. Aftermarket substitutes may not match the original calibration, potentially voiding warranties or compromising system protection. The 69W40 restores factory-specified overheat protection quickly and confidently.
